We propose an effective way to make it part of

従来、前記ステーブクーラ相互間に生じる目地、該ステーブクーラと鉄皮との間に形成される間隙内に、不定形耐火材料を充填して炉壁を構築する方法としては、特許文献１、２などにも開示されているが、不定形耐火材料の充填に先立ち、まず、ステーブクーラ相互間に、（ａ）シール用当板を取付ける方法、（ｂ）金網を取付ける方法、（ｃ）金属製の固定金物（シールプレート）を取付ける方法、などが知られている。   Conventionally, as a method for constructing a furnace wall by filling a joint formed between the stave coolers and a gap formed between the stave cooler and the iron shell with an amorphous refractory material, Patent Documents 1 and 2 are known.

JP-A-2-267205 JP 7-278626 A

従来技術による炉壁の構築、即ち、高炉の新設や改修時に、鉄皮と炉壁耐火れんがとの間に、ステーブクーラを設置したり、不定形耐火材料の吹き付けや流し込み、圧入充填によって炉壁を構築する技術は、以下に述べるような問題点があった。   When building a furnace wall according to the prior art, that is, when a blast furnace is newly installed or refurbished, a stave cooler is installed between the iron skin and the furnace wall refractory brick, or an irregular shaped refractory material is sprayed or poured into the furnace wall. The technology for constructing has the following problems.

従来技術は、ステーブクーラ相互間に、不定形耐火材料を充填するために短冊状の金属製のシールプレート５を設置する作業があり、とくに大型の高炉ではステーブクーラ１段の施工に３日も要していた。その上、該ステーブクーラ間に配設するシールプレートまわりに不定形耐火材料を圧入充填するのにも１日を要し、さらにその耐火材料の硬化にも２日を要していた。しかも、鉄皮６とステーブクーラ１、２との間に不定形耐火材料を流し込み施工したとき、流し込み材がしばしば洩れることがあった。即ち、その問題点をさらに詳しく述べると、以下のとおりである。
ａ．金属製シールプレートの施工は溶接などを伴う煩雑な工事であり、しかもそのシールプレート部への目地塞ぎのための不定形耐火材料の施工、養生、その後、鉄皮とステーブクーラとの間に生じる間隙中への不定形耐火材料の流し込み施工までに５〜６日の工事期間を必要とする。
ｂ．目地部への不定形耐火材料の流し込み不良から、鉄皮とステーブクーラとの間の間隙に充填した流し込み材がしばしば漏洩し、流し込み施工のやり直しや漏洩した流し込み材の撤去作業等、工程進捗の障害になることが多い。
ｃ．ステーブクーラ相互間の目地への不定形耐火材料の充填層の強度が低いため、操業開始の早い時期にこの充填層が炉内原料によって損傷し、これが炉内熱風ガスの通り道となり、ステーブクーラ損耗の起点となって、ステーブクーラの寿命を短かくする。
ｄ．ステーブクーラ間の目地に配設する金属製シールプレートの施工は製缶工が行うが、その後の作業は築炉工の施工担当となるため、工事の連続性が損なわれ、施工期間の延長を招く。
ｅ．ステーブクーラ相互間の目地は、施工精度により±２０ｍｍ前後の誤差があり、目地が広い場合は前記シールプレートの幅より広くなるため、鉄皮−ステーブクーラ間の間隙に不定形耐火材料を流し込んだときにその圧力に耐えられず、流し込み材の漏洩を招く一方、目地幅が狭い場合には、逆に、その金属製シールプレートが目地内に収まらず、現地でカットする必要が生じて施工作業が増える。 In the prior art, there is an operation to install a strip-shaped metal seal plate 5 between the stave coolers to fill in an irregular refractory material. Especially in a large blast furnace, a stair cooler can be installed for 3 days. It was necessary. In addition, it took one day to press-fill the irregular refractory material around the seal plate disposed between the stave coolers, and it also took two days to cure the refractory material. Moreover, when an irregular refractory material is poured between the iron skin 6 and the stave coolers 1 and 2, the casting material often leaks. That is, the problem is described in more detail as follows.
a. Construction of a metal seal plate is a complicated work involving welding, etc. In addition, it occurs between the iron skin and the stave cooler after the construction and curing of an irregular refractory material for sealing the joint to the seal plate. A construction period of 5 to 6 days is required until the irregular refractory material is poured into the gap.
b. Due to poor casting of the irregular refractory material to the joints, the casting material filled in the gap between the iron skin and the stave cooler often leaks, and the progress of the process, such as reworking the casting work and removing the leaked casting material, It is often an obstacle.
c. Since the strength of the packed bed of irregular refractory material to the joints between the stave coolers is low, this packed bed is damaged by the raw material in the furnace early in the operation, and this becomes a path for hot air gas in the furnace, and the stave cooler wears out. To shorten the life of the stave cooler.
d. The metal seal plate placed on the joint between the stave coolers is constructed by the can manufacturer, but the subsequent work is in charge of the construction of the furnace, which reduces the continuity of the construction and extends the construction period. Invite.
e. The joint between the stave coolers has an error of about ± 20 mm depending on the construction accuracy, and when the joint is wide, it becomes wider than the width of the seal plate, so an irregular refractory material was poured into the gap between the iron skin and the stave cooler. Sometimes it cannot withstand that pressure, causing leakage of the casting material, but when the joint width is narrow, the metal seal plate does not fit in the joint, and it is necessary to cut it on site. Will increase.

そこで、本発明の目的は、ステーブクーラまわりの炉壁構築作業を短期間のうちにかつ容易に、そして望ましい炉壁構造にすることができると共に、それ自身強固で炉内ガス漏洩などの障害を招くことがない高炉炉壁の構築技術を確立することにある。   Therefore, an object of the present invention is to make the furnace wall construction work around the stave cooler in a short period of time easily and to have a desirable furnace wall structure, and it is strong in itself and has problems such as gas leakage in the furnace. It is to establish the construction technology of the blast furnace wall that does not invite.

従来技術の上記課題について検討するうちに、発明者らは、金網や金属製シールプレートを用いてステーブクーラ相互間の目地を仮に塞ぐ方法を改め、それらに代えて布製シールテープを用いることを思いついた。それは、従来の金属製シールプレートに代えて布地を用いると、上述した止金３やボルト４、さらには金属製シールプレート５を目地内に収容保持するという予備的な作業がない分だけ作業が簡易になると共に、不定形耐火材料の余分な水分を速やかに除去することができ、それ故にステーブクーラ間目地部の強固な封止を果すことができる。   While examining the above-mentioned problems of the prior art, the inventors have come up with the idea of using a cloth seal tape instead of a method for temporarily closing the joint between the stave coolers using a wire mesh or a metal seal plate. It was. When cloth is used in place of the conventional metal seal plate, the work is as much as there is no preliminary work of accommodating and holding the clasp 3, bolt 4, and metal seal plate 5 in the joint. In addition to simplification, it is possible to quickly remove excess moisture from the irregular refractory material, and thus to firmly seal the joint between the stave coolers.

本発明は、正に、このような知見に基づいて開発したものであって、高炉の鉄皮の内側にステーブクーラを設置すると共に、さらにその内側には耐火れんがを施工して炉壁を構築する方法において、該ステーブクーラ相互間で生じる目地および該ステーブクーラと鉄皮との間に生じる間隙に不定形耐火材料を充填するのに先立ち、隣接する該ステーブクーラの炉内側の面に布製シールテープを貼着して前記目地を塞ぎ、その後、ステーブクーラ相互間目地と該ステーブクーラと鉄皮との間の間隙に不定形耐火材料を充填することを特徴とする高炉炉壁の構築方法を要旨構成とする。   The present invention has been developed based on such knowledge. A stave cooler is installed inside the blast furnace iron skin, and a refractory brick is applied to the inside to construct the furnace wall. In this method, prior to filling the joint formed between the stave coolers and the gap formed between the stave cooler and the iron shell with an amorphous refractory material, a cloth seal is formed on the surface of the adjacent stave cooler inside the furnace. A method for constructing a blast furnace wall characterized in that a tape is attached to close the joint, and then an amorphous refractory material is filled in the joint between the stave coolers and the gap between the stave cooler and the iron skin. The summary structure.

本発明において用いる前記布製シールテープは、吸水性が良好で柔軟な素材である天然繊維もしくは有機繊維もしくは無機繊維を使った織物、編物、不織布を用いることが好ましい。   The fabric sealing tape used in the present invention is preferably made of a woven fabric, a knitted fabric, or a non-woven fabric using natural fibers, organic fibers, or inorganic fibers, which is a flexible material having good water absorption.

また、前記布製シールテープをステーブクーラの炉内側（耐火れんが側）の面に貼着する際、鋼−布での接着力が大きな接着剤、即ち、接着剪断強さが１００（Ｎ／ｃｍ２）以上、好ましくは４９０（Ｎ／ｃｍ２）以上の特性を示す接着剤を用いて接着固定することが好ましい。 Further, when the cloth seal tape is stuck on the surface of the stave cooler inside the furnace (refractory brick side), the adhesive having a large adhesive force with the steel-cloth, that is, the adhesive shear strength is 100 (N / cm 2). ) Or more, preferably using an adhesive exhibiting characteristics of 490 (N / cm 2 ) or more.

以上説明した構成に係る本発明方法を採用した場合、
ａ．金属製シールプレートを用いる煩雑な設置作業や、目地耐火物の吹き付け施工を省略することができるから、迅速な施工が可能となり、施工時間の大幅な短縮が期待できる。
ｂ．施工作業のすべてを築炉作業員だけで行うことができるようになるので、作業員の配置調整が容易となり、施工期間の短縮と施工費のコストダウンが図れる。
ｃ．柔軟な素材である布製シールテープを使用するため、流し込み用不定形耐火材料の施工時に布製シールテープが膨らみ変形を起すことより、施工時の流し込み用不定形耐火材料の施工面レベルが管理可能となり、施工が容易になる。しかも、施工後、前記シールテープをはがして、流し込み用不定形耐火材料が確実に目地に充填しているかどうかを、直に確認することが可能になり、施工管理が容易であり、かつ施工壁の品質が大幅に向上する。
ｄ．水浸透性が良好で柔軟ないわゆる吸水質可撓性のソフト布製シールテープを使用することにより、このシールテープに接触する流し込み用不定形耐火材料の水分をこのシールテープがよく吸収し揮散させるので、従来、弱点であったステーブクーラ間目地の炉内面側がより緻密で低水分の強固な目地を形成することができる。即ち、ステーブクーラ損耗の起点となる目地部耐火物の強度アップを果すことができ、ステーブクーラ寿命が大幅に向上する。
ｅ．ステーブクーラ相互間の目地精度に影響されることなく、短時間で確実に流し込み用不定形耐火材料に対するシールが可能となる。
などの効果を得ることができる。 When the method of the present invention according to the configuration described above is adopted,
a. Since complicated installation work using a metal seal plate and spraying construction of joint refractories can be omitted, rapid construction is possible, and a drastic reduction in construction time can be expected.
b. Since all the construction work can be performed only by the furnace construction worker, it is easy to adjust the arrangement of the workers, and the construction period can be shortened and the construction cost can be reduced.
c. Since the fabric sealing tape, which is a flexible material, is used, the construction surface level of the casting amorphous refractory material for casting can be controlled because the fabric sealing tape swells and deforms during the construction of casting irregular refractory material. Construction becomes easy. In addition, after construction, it is possible to peel off the sealing tape, and directly check whether or not the irregular refractory material for pouring is filled in the joints, construction management is easy, and construction walls The quality of the is greatly improved.
d. By using so-called water-absorbent flexible soft cloth sealing tape that has good water permeability and softness, the sealing tape absorbs and volatilizes the moisture of the unshaped refractory material for pouring that comes into contact with the sealing tape. The furnace inner surface side of the joint between the stave coolers, which has been a weak point in the past, can form a dense joint with a finer and lower moisture content. That is, the strength of the joint refractory that becomes the starting point of wear of the stave cooler can be increased, and the life of the stave cooler is greatly improved.
e. Without being affected by the joint accuracy between the stave coolers, it is possible to reliably seal against the irregular refractory material for pouring in a short time.
Such effects can be obtained.

図３は、本発明の一実施形態を例示するものであり、鉄皮２１と、この鉄皮から所定の間隔をおいて配置されるカーボンれんがなどからなる炉壁耐火れんが（図示省略）との間に、炉体冷却用ステーブクーラ２２、２３を設置したもようを示している。この図からも明らかなように、本発明は、上下・左右に隣り合うステーブクーラ２２、２３相互間で形成される目地Ｓ１部分を塞ぐために、布製シールテープ２４を利用する点に特徴がある。 FIG. 3 illustrates one embodiment of the present invention, and includes an iron shell 21 and a furnace wall refractory brick (not shown) made of carbon brick and the like arranged at a predetermined interval from the iron shell. In the meantime, the furnace body cooling coolers 22 and 23 are shown. As is apparent from this figure, the present invention is to seal the joint S 1 portion formed between the staves cooler 22 and 23 mutually adjacent in the vertical and horizontal, is characterized in that it utilizes a fabric seal tape 24 .

即ち、本発明に係る構築方法では、まず、図４に示すように、鉄皮２１の内側に配設されたステーブクーラ２２、２３間の目地Ｓ１の炉内側の部分を封塞するため、前記布製シールテープ２５を該ステーブクーラ２２、２３の炉内側の面に接着剤２４を介して接着する。なお、通常の目地の間隔は、２０ｍｍ〜５０ｍｍ程度であり、この程度の間隙を塞ぐには前記布製シールテープで十分な強度が得られる。 That is, in the construction method according to the present invention, first, as shown in FIG. 4, in order to seal the inner portion of the joint S 1 between the stave coolers 22 and 23 disposed inside the iron skin 21, The cloth seal tape 25 is bonded to the inner surface of the stave coolers 22 and 23 through an adhesive 24. In addition, the space | interval of a normal joint is about 20 mm-50 mm, and sufficient intensity | strength is obtained with the said fabric sealing tape in order to block | close this space | gap.

本発明方法では、次に、炉内側が前記布製シールプレートにて塞がれた目地Ｓ１を含め、このステーブクーラ２２、２３と鉄皮２１との間隙Ｓ２の両方の空間に、流し込み用不定形耐火材料を一挙に流し込み施工し、または吹き付け施工などによって充填する。
なお、このステーブクーラ２２、２３の炉内側は、その後、炉壁耐火れんがを積み上げることにより完成された高炉の炉壁を構築することができる。 In the method of the present invention, next, for pouring into both spaces of the gap S 2 between the stave coolers 22, 23 and the iron skin 21, including the joint S 1 whose inside of the furnace is closed with the cloth seal plate. A non-standard refractory material is poured at once, or filled by spraying.
In addition, the furnace wall of the blast furnace completed by stacking the furnace wall refractory bricks can be constructed on the inside of the furnace of the stave coolers 22 and 23 thereafter.

本発明において、特徴的な構成である布製シールテープとしては、柔軟なソフト素材である天然繊維もしくは有機繊維もしくは無機繊維を使った織物、編物、不織布などを用いることが好ましい。より好ましくは、吸水性が良好で柔軟なソフト素材である有機繊維もしくは無機繊維を使った織物、編物、不織布などを用いることが好ましい。すなわち、水浸透性の大きいシート状布を用いる。例えば、キャンバス（帆布）地やデニム地等の厚地の織物で吸水性の高いものが好適である。   In the present invention, it is preferable to use a woven fabric, a knitted fabric, a non-woven fabric or the like using natural fibers, organic fibers, or inorganic fibers, which are soft soft materials, as the fabric sealing tape having a characteristic configuration. More preferably, it is preferable to use a woven fabric, a knitted fabric, a non-woven fabric or the like using an organic fiber or an inorganic fiber which is a soft material having good water absorption. That is, a sheet-like cloth having high water permeability is used. For example, a thick woven fabric such as canvas or denim is preferred.

このように、吸水性、即ち、水浸透特性の良好な布製シールテープ２５を用いると、流し込み材である不定形耐火材料２６中の水分が、この布製シールテープ２５に隣接する部分から炉内側に脱水していくので、前記目地Ｓ１中の不定形耐火材料の部分が緻密な充填耐火物となり、耐火物強度の上昇、ひいては耐火物寿命の向上に寄与する。 As described above, when the cloth seal tape 25 having good water absorption, that is, good water permeation characteristics is used, moisture in the amorphous refractory material 26 that is a casting material moves from the portion adjacent to the cloth seal tape 25 to the inside of the furnace. since going to dehydration, part of the amorphous refractory material in the joint S 1 is becomes dense packing refractories, increased refractory strength, thus contributing to the improvement of the refractory life.

しかも、このとき、図４（ｃ）に示すように、布製シールテープ２５は、この素材の可撓製（柔軟性）に起因して、高水分含有不定形耐火材料を充填した時に、変形して炉内側に膨らむものの、該不定形耐火材料の脱水により収縮することから、この膨らみと収縮とがバランスして、所期した目地面を形成することができる。   In addition, at this time, as shown in FIG. 4 (c), the cloth sealing tape 25 is deformed when filled with a high moisture content amorphous refractory material due to the flexibility (flexibility) of the material. Although it expands to the inside of the furnace, it shrinks by dehydration of the amorphous refractory material, so that the expansion and contraction can be balanced to form the intended joint surface.

なお、このような施工を担保するために、本発明では、前記布製シールテープ２５をステーブクーラ２２、２３に強固に接着する必要がある。この要求に応えられる接着剤２４としては、前記布製シールテープをステーブクーラの炉内側（耐火れんが側）に貼着する際、接着力（鋼―布）の大きな接着剤、好ましくは接着剪断強さが１００（Ｎ／ｃｍ２）程度以上、好ましく４９０（Ｎ／ｃｍ２）以上の特性を示す接着剤を用いる。例えば、ポリアミドアミンを硬化剤とするエポキシ樹脂接着剤、変成脂肪族ポリアミンや変性ポリアミド樹脂、ポリアミドアミンを硬化剤とする変性エポキシ樹脂などの可撓性エポキシ樹脂が好適に用いられる。 In order to secure such construction, in the present invention, it is necessary to firmly bond the cloth seal tape 25 to the stave coolers 22 and 23. As the adhesive 24 that can meet this requirement, an adhesive having a large adhesive force (steel-cloth), preferably adhesive shear strength, when the cloth sealing tape is attached to the inside of the furnace (the refractory brick side) of the stave cooler. Is an adhesive having a characteristic of about 100 (N / cm 2 ) or more, preferably 490 (N / cm 2 ) or more. For example, a flexible epoxy resin such as an epoxy resin adhesive using a polyamide amine as a curing agent, a modified aliphatic polyamine or a modified polyamide resin, or a modified epoxy resin using a polyamide amine as a curing agent is preferably used.

上述した図３、図４に示す本発明に適合する方法で、ステーブクーラまわりの炉壁を構築したところ、大型高炉でのステーブクーラ１段当たりの不定形耐火材料充填施工作業期間が、従前は１週間かかっていたが、３日間で施工を終了することができた。また、ステーブクーラの寿命も一般には２０〜２５年であるが、本発明方法に従って施工したものでは、それ以上の寿命が期待できるものと推定される。   When the furnace wall around the stave cooler is constructed by the method according to the present invention shown in FIG. 3 and FIG. 4 described above, the construction work period for filling the amorphous refractory material per stage of the stave cooler in the large blast furnace is Although it took one week, the construction was completed in three days. Moreover, although the life of a stave cooler is generally 20 to 25 years, it is presumed that a life longer than that can be expected when the construction is performed according to the method of the present invention.

本発明は、高炉の炉壁構築方法であるが、前記吸水質可撓性の布製シールテープを使って目地をシールして流し込み用不定形耐火材料を充填するような他の冶金用炉の炉壁耐火物施工技術としても利用が可能である。   The present invention relates to a method for constructing a furnace wall of a blast furnace, which is a furnace for other metallurgical furnaces that seals joints using the water-absorbent flexible cloth sealing tape and is filled with an irregular refractory material for pouring. It can also be used as a wall refractory construction technology.
